Definitions

  • the present invention refers to an electronic watch including circuits for time measurement and display, and for measuring a reaction time, futher including circuits controlling the display of a signal determined by comparing the measured reaction time with a reference time.
  • the watch enables a vehicle driver to measure his time of reaction or reflex and thereby assess his capacity for driving the vehicle.
  • the display of the watch can advantageously comprise means for displaying words like "DO NOT DRIVE", giving automatically and directly an answer to the question whether the attentiveness of the person conducting the test is sufficient for driving a vehicle or not.
  • the watch as shown in the FIGURE comprises an oscillator 1 and a divider 2 for suitably dividing the frequency of oscillator 1 to provide clock signals for enabling the display of time and other watch functions.
  • a suitable frequency e.g. 128 Hz is delivered by divider 2 and fed to a gate circuit 3 enabled by its control circuit 4, which is controlled by push-button 5.
  • the output of circuit 3 is connected to the input of a counter 6, which can take the form of a divider.
  • the outputs of counter 6 are connected to inputs of a comparing circuit 7 for comparing the state of counter 6 to that of an adjustable memory 8.
  • the comparing circuit 7 controls a display 9.
  • the watch comprises also a low frequency pulse generator 10, e.g. an astable multivibrator oscillating at a frequency of 0.2 Hz.
  • the output of this pulse generator 10 controls on one hand the counter 6 by resetting it to zero by every pulse delivered by the pulse generator.
  • the output of generator 10 controls a monostable circuit 11, which itself controls a display or signalling unit 12 generating a luminous or acoustical signal for every pulse coming from generator 10.
  • the watch can also comprise a supply circuit for the circuits 3 and 6 through 12 for activating these circuits only when the bearer of the watch intends to check his capacity or attentiveness.
  • the generator 10 When the circuits 3 and 6 through 12 are activated, the generator 10 generates pulses at intervals of 5 second, so that a luminous or acoustic signal is produced at 5 second intervals by the display or signalling unit 12.
  • the counter 6 is reset to zero by every pulse of generator 10. During the interval between these pulses the output signal of divider 2 transmitted to counter 6 by the gate circuit 3 advances it to a determined state; then it is reset by the next pulse coming from the generator 10. Every time that the counter 6 exceeds a counting state corresponding to a state stored in the memory 8, the comparing circuit 7 transmits a signal to the display 9, which is activated until counter 6 is reset.
  • the bearer of the watch presses the push-button 5 as fast as possible after the appearance of a signal on the display unit 12; at this instant the passage of the signal of divider 2 to counter 6 is interrupted in the gate circuit 3 and counter 6 stops in a state depending on the reaction time between the appearance of the signal on the display unit 12 and the activating of the control circuit 4 by push-button 5.
  • the output of the comparison circuit 7 and the display 9 are activated or not.
  • the display 9 is activated and indicates to the bearer of the watch by the words "DO NOT DRIVE" that he should not drive a vehicle.
  • the counter 6 After 5 seconds the counter 6 is reset by the next pulse of the generator 10 and the display 9 is extinguished if it had been activated.
  • a circuit not shown can be provided for transmitting the information of the output of the comparison circuit 7 to the display 9 when the push-button is activated, and for storing this information until the next pulse of generator 10 is received.
  • the circuits take up their initial functions described above and the bearer of the watch can repeat the test of his reaction time.
  • the push-button 5 and the switch controlled by it can control another function of the watch, e.g. the lighting of the time display.
